Today, Wind Turbine OEMS utilize design load cases for the design and certification of wind turbines. These load cases are applied to ensure that turbines operate in a stochastic environment for at least 20 years.
However, reliability analysis should not stop at the design stage. Once a turbine is commissioned, consequent reliability analysis should also be conducted in order to understand how long a turbine will truly last at an installed location with the exposed environmental conditions.

Investigating Microstructural Alterations Leading to White Etch Cracks (WEC's...Sentient Science
This webinar outlines Sentient's development on their White Etching Crack capabilities to current materials-based prognostics life prediction models to better predict wind turbine gearbox life.
The formation of white etching cracks (WEC's) in bearings are known to be one of the major failure modes associated with gearbox failure. WEC's can casue premature failures in rolling element bearings occuring as early as 1-20% of the calculated L10 life.
According to the National Renewable Energy Laboratory's (NREL) gearbox failure database, 64% of gearboxes failed due to bearings and 25% due to gear failures. These failures are causing increased downtime and costly repairs.
The webinar outlines microstructrual alterations detected in LSIS and HSIS bearings and how microstructural alterations impact damage in gearboxes.
Moventas GE 1.5 Extra Life Gearbox Achieves 4x LifeSentient Science
The presentation outlines the upgrades Moventas made on the GE 1.5 Extra Life gearboxes.
Sentient Science validated the technology advances and life extension claims for the owner operator community and quantified the improvements in performance, durability and reliability.
The computational testing showed an overall life improvement by a factor of 4x. The life extension achieved was due to improvements made to the case carburized ring gear, integrated planet gear bearings, high speed stage bearings, tooth surface roughness, and material specification upgrades in both bearings and gears.

According to a report by Windpower Engineering & Development, the cost to repair main bearings is one of the highest compared to other turbine systems ranging from $150,000 to $300,000. As fielded turbines age, the aggregated downtime has increased to more than 20,000 hours.
The presentation features:
- New capabilities in the DigitalClone Live software that predict early wear initiation in the main bearing raceways and rollers.
- How to understand the current health of the main bearing in a particular asset to mitigate damage prior to failure.
- How to reduce the cost of repair, currently ranging from $150K - $300K for each occurrence, and reduce the amount of downtime.

Imminent DEATH from SCADA New Product IntroductionSentient Science
An introduction of new Imminent DEATH product from SCADA.
By now, you have heard about our lifing and life extension products. Join us for a webinar to discuss how we are marrying our imminent death product that understands the last months of an asset, component life including blades, gearboxes, main bearings, pitch bearings, generators, and other rotating equipment with our current life extension products. By doing this, you can better achieve a savings of 13% revenues or, specifically for the energy industry,1 cent per kW hour.
Gerald Curtin, Vice President of Asset Answers reviews the imminent death product and outlines the benefits of integrating SCADA data with material science models.
When it comes to offshore wind energy technology, most innovations are dedicated to foundations or construction techniques to lower LCOE by lowering CapEx and OpEx, but we are reaching an inflection point and AEP needs to be prioritized. Wind park controls and operations methods for revenue and power maximization being developed for onshore wind will be fundamentally necessary to leverage in order to drive maximum offshore LCOE benefit as the CapEx impact on reducing LCOE slows down in the coming years.

RADIOSS, 27 years of past evolution and futureAltair
In the seventies crash simulations in automotive, helicopter & plane industries were done at the concept phase with implicit nonlinear code using beam and spring models. At the same time high speed impacts were solved with finite difference codes with explicit time integration. In the eighties it took several years for the automotive engineers to validate and accept explicit codes to solve car crashes. This was made possible thanks to the power of CRAY vector computers. In the nineties crash became a Computer Aided Engineering (CAE) driven design process in the automotive industry. Simulation driven design process allows design engineers to test many alternatives at a fraction of prototype test cost. Today explicit code is standard for crash simulation and this paper describes the past evolution of the method in the RADIOSS code. In the nineties RADIOSS was successfully applied to stamping and manufacturing processes, implicit time integration was introduced to speed-up quasi static analysis and to performed elastic return or gravity setting using the same code. From the beginning an Arbitrary Lagrange Euler (ALE) integration scheme was built in RADIOSS allowing to solve several Fluid Structure Interaction (FSI) problems. RADIOSS is today a general purpose non-linear finite element code with several applications in automotive, aerospace, defense, nuclear, civil engineering and consumer goods industries.

Utilizing Predictive Modeling for Bearing Supplier Decision MakingSentient Science
Machinery OEMs often have to choose between different bearing suppliers when designing a new device. Although the same bearing model from different suppliers may have the same external form factor and load rating, there are often differences in internal geometry, material quality, and surface treatment from one supplier to another that will cause the performance and expected life to vary in the field.
These slides will outline Sentient Science’s approach towards measuring and quantifying these hidden bearing parameters. We show how we combine material, geometry, and surface treatment metrics into high-fidelity predictive models which we use to help OEMs decide which bearing supplier to choose for their application.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
